法律研究Python Pandas - 检查 CustomBusinessHour 偏移量是否已标准化
如需检查 CustomBusinessHour 偏移量是否已标准化，可在 Pandas 中使用 CustomBusinessHour.normalize 属性。
首先，导入所需的库 −
import pandas as pd
在 Pandas 中设置时间戳对象 −
timestamp = pd.Timestamp('2021-10-25 08:35:10')
创建 CustomBusinessHour 偏移量。CustomBusinessHour 是 DateOffset 子类。我们使用“normalize”参数标准化了 CustomBusinessDay −
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 3, weekmask = 'Mon Tue Wed Fri Sat' ,normalize=True)
将偏移量添加到时间戳并显示更新的时间戳 −
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)
检查 CustomBusinessHour 偏移量是否已标准化 −
print("\nThe CustomBusinessHour Offset is normalized ?\n", cbhOffset.normalize)示例
以下是代码 −
import pandas as pd
# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-10-25 08:35:10')
# Display the Timestamp
print("Timestamp...\n",timestamp)
# Create the CustomBusinessHour Offset
# CustomBusinessHour is the DateOffset subclass
# Weekmask of valid business days
# We have normalized the CustomBusinessDay using the "normalize" parameter
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 3, weekmask = 'Mon Tue Wed Fri Sat',normalize=True)
# Display the CustomBusinessHour Offset
print("\nCustomBusinessHour Offset...\n",cbhOffset)
# Add the offset to the Timestamp and display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)
# Return frequency applied on the given CustomBusinessHour Offset object as a string
print("\nFrequency applied on the given CustomBusinessHour Offset object...\n",cbhOffset.freqstr)
# return the name of the frequency applied on the given CustomBusinessHour object
print("\nThe name of the frequency on the CustomBusinessHour object..\n", cbhOffset.name)
# check whether the CustomBusinessHour Offset is normalized or not
print("\nThe CustomBusinessHour Offset is normalized ?\n", cbhOffset.normalize)输出
这将生成以下代码 −
Timestamp... 2021-10-25 08:35:10 CustomBusinessHour Offset... <3 * CustomBusinessHours: CBH=09:00-17:00> Updated Timestamp... 2021-10-25 00:00:00 Frequency applied on the given CustomBusinessHour Offset object... 3CBH The name of the frequency on the CustomBusinessHour object.. CBH The CustomBusinessHour Offset is normalized ? True
